Blockchain Videos – Tutorials for Dummies!

Information related to the blockchain technology is very scattered. I would like to share some videos that help me to understand the fundamentals of blockchain technology. There are thousands of videos on the web. However, sometimes the quality and content are very poor. Check this introductory videos to get to know the posibilities of this new technology.

The most successful cryptocurrency nowadays is Bitcoin. It was proposed and implemented under the pseudonym of Satoshi Nakamoto in 2009. Blockchain is the core technology that supports Bitcoin. It solves the double-spending problem. Basically, it is a decentralized database (or ledger) that allows digital transactions in a trustless environment. This ledger is replicated and shared among the members of a network. Transactions are permanently stored in a chain of blocks since inception. Members of the network legitimize these transactions through a consensus mechanism. If something changes in one machine, then it changes everywhere. It is computationally infeasible to fake a block but it is very easy to detect the fake block. Therefore, a trusted third party is no longer needed.

Blockchain has great potential to become the fifth disruptive computing paradigm after mainframes, PCs, the Internet, and mobile/social networking. According to M. Swan, blockchain has potential as a worldwide, decentralized record for the registration, inventory and transfer of all assets-not just finances, but property and intangible assets such as votes, software, health data and ideas.
